Aim: To evaluate outcomes related to antiplatelet therapy in patients with ST-elevation myocardial infarction (STEMI) admitted to the San Gerardo Hospital in Monza, an extracorporeal membrane oxygenation (ECMO) reference center in the Monza-Brianza area. Methods: This retrospective study enrolled patients with STEMI hospitalized between 2013 and 2017. Results: This study included 653 patients (mean age: 67.5 years, 71% male). Across the study period, ticagrelor use showed consistent increases, from 22% of patients during 2013 to 85% in 2017. Cardiac arrest prehospitalization occurred in 100 patients (15.3%), either at home (n = 85, 13.0%) or during transfer (n = 15, 2.3%); 46 patients underwent ECMO for refractory cardiac arrest. Rates of 90-day survival (hazard ratio [HR]: 2.4, 95% confidence interval [CI]: 1.3-4.4, P = .004) and ST resolution (odds ratio [OR]: 2.5, 95% CI: 1.6-4.1, P = .000) were higher with ticagrelor than with other antiplatelet agents. When analyzed by each agent, patients on ticagrelor had longer survival (HR: 0.4, 95% CI: 0.2-0.8, P = .008) than patients on clopidogrel and more frequent ST resolution than those on clopidogrel or prasugrel (OR: 0.4, 95% CI: 0.2-0.7, P = .002 and OR: 0.4, 95% CI: 0.2-0.7, P = .006). There was no difference in mortality between ticagrelor and prasugrel. Conclusions: Changes in the treatment of high-risk patients with STEMI over time are in line with changes in treatment guidelines. In these patients, ticagrelor is associated with significantly improved 90-day mortality compared with clopidogrel.

Deformation behavior and texture development of NiMnGa ferromagnetic shape memory alloy (FSMA) particles embedded polymer composites were investigated by compression tests and X-ray diffraction pole-figure analysis (XRD-PF). Both the NiMnGa/silicone and NiMnGa/epoxy composites exhibited a characteristic three-stage deformation which is often seen in shape memory alloys due to martensite variant reorientation. XRD-PF revealed that (004) texture was developed in the compressed NiMnGa/silicone due to the retention of martensite variant reorientation. On the other hand, significant texture change was not recognized in the compressed NiMnGa/epoxy. Rearranged martensite variants was kept after unloading in silicone matrix having low Young's modulus, but reverse reorientation occurred in epoxy matrix with high Young's modulus. The rearrangement behavior of martensite variants is strongly affected by elastic properties of matrix.

This study explored factors associated with age of identification of autism spectrum disorder (ASD). Results of a one-way ANOVA indicated differences in age of diagnosis among the four regions in the United States, F(3, 650) = 7.618, p = .01. Tukey’s post hoc comparisons of the groups indicated that the mean age of diagnosis in the Midwest ( M = 38.9 months or 3 years, 3 months) was significantly later than in the Northeast ( M = 32.75 months or 2 years, 9 months, p = .000) and South ( M = 33.26 months or 2 years, 9 months, p = .000). Results of a Pearson correlation indicated a significant negative correlation ( r = −.409, n = 654, p = .000) between date of birth and age of diagnosis, with more recent birthdays associated with lower age of diagnosis. Regression results were statistically significant, F(25, 620) = 7.549, p < .001, R2 = .233, with some factors predicting earlier age of diagnosis and some factors predicting later diagnosis.

Objectives:The aims of this study were to assess the 1-year cost-effectiveness of a new combined immunosuppressive and anti-infectious regimen in kidney transplantation to prevent both rejection and infectious complications.Methods:Patients (pts) transplanted from January 2000 to March 2003 (Group A) and treated with a conventional protocol were compared with pts submitted to a combined regimen including universal cytomegalovirus (CMV) prophylaxis between April 2003 and July 2005 (Group B). Costs were computed from the hospital accounting system for hospital stays, and official tariffs for outpatient visits. Patients with incomplete costs data were excluded from analysis.Results:Fifty-three patients were analyzed in Group A, and 60 in Group B. Baseline characteristics including CMV serostatus were not significantly different between the two groups. Over 12 months after transplantation, acute rejections decreased from 41.5 percent in Group A to 6.7 percent in Group B (p&lt; .001), and CMV infections from 47 percent to 15 percent (p&lt; .001). Overall, readmissions decreased from 68 percent to 55 percent (p= .160), and average hospital days from 28 ± 19 to 20 ± 11 days (p&lt; .007). The average number of outpatient visits decreased from 49 ± 10 to 39 ± 8 (p&lt; .001). Average 1-year immunosuppressive and CMV prophylaxis costs (per patient) increased from CHF20,402 ± 7,273 to 27,375 ± 6,063 (p&lt; .001), graft rejection costs decreased from CHF4,595 ± 10,182 to 650 ± 3,167 (p= .005), CMV treatment costs from CHF2,270 ± 6,161 to 101 ± 326 (p= .008), and outpatient visits costs from CHF8,466 ± 1’721 to 6,749 ± 1,159 (p&lt; .001). Altogether, 1-year treatment costs decreased from CHF39’957 ± 16,573 to 36,204 ± 6,901 (p= .115).Conclusions: The new combined regimen administered in Group B was significantly more effective, and its additional costs were more than offset by savings associated with complications avoidance.

Longer and more intensive postinduction intensification (PII) improved the outcome of children and adolescents with “higher risk” acute lymphoblastic leukemia (ALL) and a slow marrow response to induction therapy. In the Children's Cancer Group study (CCG-1961), we tested longer versus more intensive PII, using a 2 × 2 factorial design for children with higher risk ALL and a rapid marrow response to induction therapy. Between November 1996 and May 2002, 2078 children and adolescents with newly diagnosed ALL (1 to 9 years old with white blood count 50 000/ or more, or 10 years of age or older with any white blood count) were enrolled. After induction, 1299 patients with marrow blasts less than or equal to 25% on day 7 of induction (rapid early responders) were randomized to standard or longer duration (n = 651 + 648) and standard or increased intensity (n = 649 + 650) PII. Stronger intensity PII improved event-free survival (81% vs 72%, P < .001) and survival (89% vs 83%, P = .003) at 5 years. Differences were most apparent after 2 years from diagnosis. Longer duration PII provided no benefit. Stronger intensity but not prolonged duration PII improved outcome for patients with higher-risk ALL. This study is registered at http://clinicaltrials.gov as NCT00002812.

Aims: The study examines the factors related to the appraisal and adherence of the individual and public health preventive measures. Background: The effectiveness of the measures battling the pandemic was largely determined by the voluntary compliance of the public. Objectives: This study aimed to identify psychological perception factors related to the appraisal of individual measures and endorsement of public health measures during the early stage of the COVID-19 pandemic among Chinese living in Canada. Methods: A convenience sample of 656 participants completed an online survey. Nonparametric Kruskal Wallis tests were used to compare COVID perception variables (e.g., perceived susceptibility, fear, perceived severity, and information confusion) among different sociodemographic subgroups. Bootstrapped regression models were used to assess the association of these variables with outcome measures. Results: Compared to their counterpart groups, lower perceived susceptibility was reported by adults 65 years and older (p = .002) or retired (p = .015); greater fear was reported by females (p = .044), those with lower education (p = .001), and Mainland Chinese (p = .033); greater perceived severity was reported by individuals with lower education and smaller household size (ps = .003). Perceived susceptibility was inversely associated with individual measure appraisal (p = .032). Perceived severity was positively associated with individual measure appraisal (p = .005) and public measure endorsement (p < .001). Conclusion: Individual behaviour measure appraisal was predicted by lower perceived susceptibility and higher perceived severity, whereas public health measure endorsement was related to higher perceived severity. These results inform the public and the policymakers about the critical factors that affect the preventive measure appraisal and endorsement.

656 Background: Patients (pts) with peritoneal metastases from CRC (pmCRC) have reduced OS compared to mCRC pts without peritoneal involvement. Here we further investigated the impact of number and location of metastases among pts receiving first-line systemic chemotherapy. Methods: Individual patient data were available on 9,265 pts (median age 64; 63% male; 93% ECOG PS 0-1; 68% colon primary tumor; brain metastases excluded) enrolled onto 12 first-line randomized trials (4 tested targeted regimens). Stratified multivariable Cox models were used to assess the associations with overall survival (OS); adjusted hazard ratios (HRadj) and 95% confidence intervals are reported (CI). Results: There were 7,963 (86%) pts with non-pmCRC (3,904 with one disease site; 4,059 with ≥2 disease sites), 191 (2%) pts with isolated pmCRC, and 1,111 (12%) non-isolated pmCRC. These groups were similar in age, race, and use of targeted chemotherapy. Compared to non-pmCRC, pts with pmCRC were more likely to be female (41% vs. 36%, p<.001), have colon primary tumors (85% vs. 67%, p<.0001), and have PS2 (10% vs. 6%, p<.0001). Compared to isolated pmCRC, pts with solitary non-peritoneal sites (both M1a) had significantly better OS (HRadj=0.78; CI, 0.64-0.94, p=.009) while pts with ≥2 non-peritoneal sites had similar OS (HRadj=1.06; CI 0.88-1.28, p=.535). OS of pts with pmCRC with a single other disease site (n=446) was similar to isolated pmCRC (HRadj=1.13; CI 0.91-1.40, p=.28), but those with pmCRC + ≥2 additional disease sites (n=665) had shortest survival (HRadj=1.44; CI 1.17-1.77, p<.001). A combination of peritoneal and liver metastases (n=821; HRadj=1.37, CI 1.12-1.67, p=.002) was associated with poorer survival compared with isolated pmCRC; but combination with extrahepatic sites (n=290; HRadj=1.15, CI 0.91-1.45, p=.25) was not. Conclusions: pmCRC pts have significantly worse survival than those with other solitary site mCRC. Among those with multiple disease sites, poorer survival is a function of increased number of metastatic sites and peritoneal involvement, which indicates prognostic heterogeneities among M1b pts.

AbstractObjectivesTo investigate the association between cognitive impairment and hospitalizations, quality of life and satisfaction with life among patients with schizophrenia.MethodsA point-in-time survey was conducted between July and October 2019 via the Adelphi Schizophrenia Disease Specific Programme across the USA. Patients were stratified as mild or severe based on the level of cognitive impairment reported by their psychiatrist (normal, mild = mild; moderate, severe, very severe = severe). Multiple regression analysis was used to model the association between cognitive impairment and outcomes, adjusting for baseline characteristics.ResultsData were provided by 124 psychiatrists for 651 mildly and 484 severely impaired patients with schizophrenia; PSCs were completed by 349 mildly and 206 severely impaired patients. Severe cognitive impairment was associated with increased odds of hospitalization due to schizophrenia relapse since diagnosis (2.10 odds ratio [OR], P = .004) and within 12 months (1.95 OR, P < .001) compared to mild impairment. Moreover, patients with severe cognitive impairment had poorer quality of life according to the EuroQoL 5-dimension (EQ-5D) Health Index (−0.085 coefficient, P < .001) and EQ-5D Visual Analogue Scale (−6.24 coefficient, P = .041) compared to patients with mild cognitive impairment. Severe cognitive impairment was also associated with lower overall life satisfaction according to the Quality-of-Life Enjoyment and Satisfaction Questionnaire (−8.13 coefficient, P = .006) compared to mild cognitive impairment.ConclusionSchizophrenia patients with severe cognitive impairment had more hospitalizations due to relapse than patients with mild cognitive impairment. Additionally, patients with severe cognitive impairment had significantly lower quality of life and overall satisfaction with life compared to patients with mild cognitive impairment.FundingSunovion Pharmaceuticals

The aim of the work is to analyze and evaluate the current state of knowledge in the field of rotary tables, to create a table design according to the assignment and its 3D model with part of the drawing documentation. The theoretical part of the work searches for solutions used in the construction of rotary tables in the category of table according to the assignment. The information obtained is further used in the design of rotary table solution variants. By evaluating the weight of the required properties and their degree of fulfillment, a variant of the design solution of the table is selected, which is then designed. The individual design steps are described and explained in the text part of the work accompanied by pictures and calculations. The result of the process is a structural design of the mechanical part of the rotary table with a 3D model and partially processed drawing documentation. The contribution of the work is the summarization of relevant information for the design of rotary tables, the processed procedure of solving the design of the table and the modeled design of the rotary table. These outputs can be further treated as documentation for the production of the designed table, the development of the rotary table design to deeper details or technical development in this area.

A presente pesquisa enfoca a utilização de formas paramorfogênicas de diferentes linhagens de Pleurotus ostreatus para remover o corante reativo Procion Blue MXG de soluções aquosas. O fungo induzido fisicamente em sua forma paramorfogênica (pellets) foi usado no estudo da biosorção do corante em diferentes valores de pH e em comparação entre as hifas autoclavadas e não autoclavadas, visando a remoção do mesmo em solução aquosa. O corante reativo Procion Blue MXG foi analisado em sua estabilidade espectral em diferentes valores de pH. Este corante se mostrou instável em termos de estabilidade espectral. O pH que melhor se enquadrou quanto à capacidade de remoção das biomassas pelletizadas foi o 2,50, tanto para amostras autoclavadas como não autoclavadas Em praticamente todos os experimentos de interação entre a biomassa e o corante, as autoclavadas apresentaram maior capacidade biosortiva do que as não autoclavadas. Foram também efetuados estudos comparativos a respeito das equações Isotermas de adsorção de Freundlich e Langmuir. A comparação entre os coeficientes de correlação de ambas, nas condições de 30º C e pH 2,50 indicam que a equação de Langmuir explica melhor a interação entre aa biomassa fúngica e o corante estudado em todas as linhagens, quando não autoclavadas, admitindo-se tratar de um processo biosortivo em monocamada. Para as amostras autoclavadas, a equação de Langmuir também é válida para a linhagem CCB 010, sendo que para as linhagens CCB 004 e CCB 650, a equação de Freundlich prevaleceu. Os testes de biosortividade em termos de varredura espectral indicam que as linhagens CCB 010 e CCB 650 apresentam tendência de ter potencial enzimático para degradar o corante, principalmente em pH 2,50. Pelos dados apresentados, podemos afirmar que, do ponto de vista de biosorção, o Pleurotus ostreatus e... , was used in the dye's biosorption study, in different values of pH and in comparasion between alive and dead fungi micelia, aiming at its removal in watery solution. The reactive dye Procion Blue MXG was analyzed in its spectral stability in different values of pH. This dye was showed as unstable in terms of spectral stability. The pH that has better fits in the capacity of removal of biomass was the 2,50, as much for dead samples as for alive samples. In practically all the experiments of interaction between the biomass and the dye, the deceased samples had presented greater biosorptive capacity than the alive ones. Also comparative studies regarding the isothermal equations of adsoption of Freundlich and Langmuir had been effected. The comparison between the coefficients of correlation of both, in the conditions of 30ºC and pH 2,50 indicates that the equation of Langmuir explains better the interaction between the fungic biomass and the dye in all the strains, when deceased, admitting itself to deal with a biosorptive process in monolayer. For the dead samples, the equation of Langmuir also is valid for strain CCB 010, being that for strains CCB 004 and CCB 650, the equation of Freundlich has prevailed.

A presente pesquisa enfoca a utilização de formas paramorfogênicas de diferentes linhagens de Pleurotus ostreatus para remover o corante reativo Procion Blue MXG de soluções aquosas. O fungo induzido fisicamente em sua forma paramorfogênica (pellets) foi usado no estudo da biosorção do corante em diferentes valores de pH e em comparação entre as hifas autoclavadas e não autoclavadas, visando a remoção do mesmo em solução aquosa. O corante reativo Procion Blue MXG foi analisado em sua estabilidade espectral em diferentes valores de pH. Este corante se mostrou instável em termos de estabilidade espectral. O pH que melhor se enquadrou quanto à capacidade de remoção das biomassas pelletizadas foi o 2,50, tanto para amostras autoclavadas como não autoclavadas Em praticamente todos os experimentos de interação entre a biomassa e o corante, as autoclavadas apresentaram maior capacidade biosortiva do que as não autoclavadas. Foram também efetuados estudos comparativos a respeito das equações Isotermas de adsorção de Freundlich e Langmuir. A comparação entre os coeficientes de correlação de ambas, nas condições de 30º C e pH 2,50 indicam que a equação de Langmuir explica melhor a interação entre aa biomassa fúngica e o corante estudado em todas as linhagens, quando não autoclavadas, admitindo-se tratar de um processo biosortivo em monocamada. Para as amostras autoclavadas, a equação de Langmuir também é válida para a linhagem CCB 010, sendo que para as linhagens CCB 004 e CCB 650, a equação de Freundlich prevaleceu. Os testes de biosortividade em termos de varredura espectral indicam que as linhagens CCB 010 e CCB 650 apresentam tendência de ter potencial enzimático para degradar o corante, principalmente em pH 2,50. Pelos dados apresentados, podemos afirmar que, do ponto de vista de biosorção, o Pleurotus ostreatus e... (Resumo completo, clicar acesso eletrônico abaixo).
The present research focuses the use of paramorphic forms of different strains of Pleurotus ostreatus, to remove the reactive dye Procion Blue MXG from aqueous solutions. This fungi induced phisically in its paramorphic form (pellets), was used in the dye's biosorption study, in different values of pH and in comparasion between alive and dead fungi micelia, aiming at its removal in watery solution. The reactive dye Procion Blue MXG was analyzed in its spectral stability in different values of pH. This dye was showed as unstable in terms of spectral stability. The pH that has better fits in the capacity of removal of biomass was the 2,50, as much for dead samples as for alive samples. In practically all the experiments of interaction between the biomass and the dye, the deceased samples had presented greater biosorptive capacity than the alive ones. Also comparative studies regarding the isothermal equations of adsoption of Freundlich and Langmuir had been effected. The comparison between the coefficients of correlation of both, in the conditions of 30ºC and pH 2,50 indicates that the equation of Langmuir explains better the interaction between the fungic biomass and the dye in all the strains, when deceased, admitting itself to deal with a biosorptive process in monolayer. For the dead samples, the equation of Langmuir also is valid for strain CCB 010, being that for strains CCB 004 and CCB 650, the equation of Freundlich has prevailed. The tests of biosorptivity in terms of spectral sweepings indicate mainly that strains CCB 004, CCB 010 and CCB 650 present trend to have enzymatic potential to degrade the dye, in pH 2,50. For the presented data, we can affirm that, of the point of view of the biosorption., paramorphic Pleurotus ostreatus and its strains offers conditions to come to be used as biosorbent substratum in the treatment of industrial effluent who contains these azo compounds.

Constraint Programming (CP) is a powerful technique for solving large-scale combinatorial (optimisation) problems. Constraint solving a given problem proceeds in two phases: modelling and solving. Effective modelling has an huge impact on the performance of the solving process. This thesis presents a framework in which the users are not required to make modelling decisions, concrete CP models are automatically generated from a high level problem specification. In this framework, modelling decisions are encoded as generic rewrite rules applicable to many different problems. First, modelling decisions are divided into two broad categories. This categorisation guides the automation of each kind of modelling decision and also leads us to the architecture of the automated modelling tool. Second, a domain-specific declarative rewrite rule language is introduced. Thanks to the rule language, automated modelling transformations and the core system are decoupled. The rule language greatly increases the extensibility and maintainability of the rewrite rules database. The database of rules represents the modelling knowledge acquired after analysis of expert models. This database must be easily extensible to best benefit from the active research on constraint modelling. Third, the automated modelling system Conjure is implemented as a realisation of these ideas; having an implementation enables empirical testing of the quality of generated models. The ease with which rewrite rules can be encoded to produce good models is shown. Furthermore, thanks to the generality of the system, one needs to add a very small number of rules to encode many transformations. Finally, the work is evaluated by comparing the generated models to expert models found in the literature for a wide variety of benchmark problems. This evaluation confirms the hypothesis that expert models can be automatically generated starting from high level problem specifications. An method of automatically identifying good models is also presented. In summary, this thesis presents a framework to enable the automatic generation of efficient constraint models from problem specifications. It provides a pleasant environment for both problem owners and modelling experts. Problem owners are presented with a fully automated constraint solution process, once they have a precise description of their problem. Modelling experts can now encode their precious modelling expertise as rewrite rules instead of merely modelling a single problem; resulting in reusable constraint modelling knowledge.

This paper describes insights into keel and rigging loads obtained through a data acquisition system fitted on the fleet of Volvo 65 yachts during the 2014-2015 Volvo Ocean Race. In the first part keel fin stress spectra are derived from traces of canting keel ram pressures and keel angle; these are reviewed and compared against equivalent spectra obtained by applying methods proposed by Det Norske Veritas - Germanischer Lloyd (“DNVGL”) guidelines and the ISO 12215 standard. The differences between stress spectra and their validity are discussed, considering two types of keel: milled from a monolithic cast of steel, and fabricated from welded metal sheets. The second part discusses predicted and actual rigging working loads for the Volvo 65 yachts, considering how safety factors vary between design loads proposed by DNVGL and actual recorded loads.

ASME Code Case N-658, “Risk-Informed Safety Classification for Use in Risk-Informed Repair/Replacement Activities” and Code Case N-660, “Alternative Repair/Replacement Requirements For Items Classified In Accordance With Risk-Informed Processes” are being completed to expand the breadth of risk-informed requirements for pressure-retaining items. This initiative, which is built from prior ASME Section XI risk-informed inservice inspection developments over the past decade, has been undertaken in conjunction with U.S. risk-informed regulation efforts. The U.S. Nuclear Regulatory Commission (NRC) is working with the industry on risk informing Title 10 Code of Federal Regulations Part 50 (10CFR50). The Nuclear Regulatory Commission’s basic proposal is to allow modification of some of the special treatment requirements of 10CFR50. Their effort is proceeding via an Advanced Notice of Public Rulemaking, March 3, 2000, and an announcement of Availability of Draft Rule Wording, November 29, 2001, to add 10 CFR 50.69, “Risk-Informed Treatment of Structures, Systems and Components.” A parallel task by the Nuclear Energy Institute (NEI) to develop a guideline on how to implement the results of the rulemaking is also well underway via NEI 00-04 (Draft Revision B), “Option 2 Implementation Guideline,” May 2001. This paper summarizes the content and status of approval of the proposed ASME Code Cases, including how they relate to the above NRC and NEI efforts. Some initial results from trial application of the Code Cases will also be cited.

The simulation work presented herein characterizes the performance of a recuperated gas turbine (GT) hybrid systems in response to different levels of fuel utilization (Uf) by the SOFC. The SOFC performance was compared with and without anode recycle (AR), operating at 90% total stack Uf (Uf.stack). A study at 65% Uf was also considered as a reference case for the hybrid power system without anode recycle, i.e. using single-pass cell fuel utilization (Uf.cell). All three cases in this paper were evaluated at design points for a 550 MW hybrid system using coal-derived syngas feed with zero methane. A previously developed one-dimensional (1D) fuel cell model was used to simulate the distributed profile of thermal and electrochemical properties along the fuel cell length. Fuel cell total current density, average solid temperature, and cathode inlet temperature were maintained identical at each fuel utilization to avoid confounding the results with the impacts of SOFC degradation. The maximum system efficiency of 71.1% was achieved by SOFC/GT non-recycle systems at 90% Uf.cell (with 90% Uf.stack). The case at 65% Uf.cell (with 65% Uf.stack) demonstrated 70.7% total efficiency, only 0.4% point lower than at 90% Uf.cell. However, integrating anode recycle to the system significantly reduced the maximum total efficiency to 55.5%. Although the distributed SOFC performance across the cell length for 65% Uf.cell with AR at 90% Uf.stack was similar to the 65% Uf.cell (with 65% Uf.stack), recycling anode off-gas resulted in lower fuel cell Nernst potential that caused further drop in both stack and total system efficiency.

Application of thin-film thermocouples and temperature sensitive paint to surface temperature and heat transfer rate measurement on a flat plate with internal cooling is described in this paper. The test arrangement was designed to model flow and heat transfer conditions in terms of gas (external) and coolant (internal) Reynolds numbers that are typical for cooled turbine components. The test article is geometrically simple; however, from the heat transfer point of view it represents a fairly complex case. For both flows, internal and external, the hydrodynamic boundary layers start well ahead of the thermal boundary layers. The thermally active surface is preceded by an adiabatic starting length. Also, the heat transfer occurs under nonisothermal wall conditions and nonuniform heat flux conditions. The heat transfer experiments were carried out for a range of Mach number and Reynolds number on the gas side from 0.17 to 0.53 and from 135 000 to 580 000, respectively. On the coolant side, the corresponding ranges were from 0.3 to 0.52 for the flow Mach number, and from 20 000 to 65 000 for the Reynolds number. Measured bulk heat transfer rates demonstrated expected trends as functions of external (gas) and internal (coolant) Reynolds numbers. Local heat transfer rates measured along the mid-span line behaved as expected in relation to the internal (coolant) Reynolds number. However, they seem to be insensitive to changes in the external (gas) Reynolds number — at least for the particular test arrangement. Local heat transfer rates, however, strongly depend on the location with respect to the width of the cooling passage. These results were not expected; they may be caused by three dimensional nature of heat convection and conduction in this test arrangement.

Present results on intermediate temperature-operating solid oxide fuel cells (IT-SOFC) are mainly focused to obtain higher performance of single cell at lower operating temperature, especially with planar type. In order to develop a 1 kW-class SOFC system for Residential Power Generation (RPG) application that can be operated at intermediate temperatures, we have developed an anode-supported and planar type SOFC stack using cost-effective interconnects such as ferritic stainless steels. To improve electrical performance of the anode-supported SOFC, cells with alternative electrode or thin electrolyte layer of YSZ and ScSZ, respectively, were fabricated by slurry coating and their performances were investigated. Mixtures of NiO and 8YSZ powders were pressed into rectangular plates, which were pre-sintered at 1400°C for 1 h. Then the 8YSZ (8mol%Y2O3+ZrO2) or 10ScSZ (10mol%Sc2O3+1 mol%CeO2+ZrO2) electrolytes were coated by slurry coating method on the upper side of anode substrate and cofired at 1550 or 1500°C for an hour. Thereafter, composite cathode pastes of LSM (La0.7Sr0.2MnO3) or LSCF ((La0.6Sr0.4)(Co0.2Fe0.8)O3 ) were screen-printed on thin electrolytes and heat-treated at 1100°C for 2 h. The final size of anode-supported single cell sintered was about 5 × 5 cm2, and the thickness of the electrolyte and the cathode layer was about 20 μm and 30 μm, respectively. The I-V and AC impedance characteristics of these single cells were evaluated at intermediate temperature (650 ∼ 750°C) using hydrogen gas as a fuel. The maximum power density of anode-supported cell was 0.4 ∼ 1.7 W/cm2 at 750°C and 0.12 ∼ 0.55 W/cm2 at 650°C depending on the composition and microstructure of electrolyte/electrodes.

Palm Methyl Ester (PME) is an attractive alternate fuel to petroleum diesel because it can be produced from a renewable source, is close to being carbon-neutral in the environment, and has many properties similar to those of petroleum fuels. Although a few engine studies have been completed using PME, basic studies on the combustion of PME sprays are limited. Hence, the objective of this investigation was to study the combustion characteristics of spray flames of PME and diesel at three equivalence ratios: 0.4, 0.6 and 0.8. The liquid fuel was atomized and combusted with air in a heated environment; the coflow air temperature was maintained at 65% of the midpoint of the boiling point range of the fuels. The equivalence ratio was changed by altering the fuel flow rate, while maintaining the atomizing and coflow air flow rates constant, thus maintaining the gas velocity field invariant. The PME flames were shorter and less luminous than the diesel flames and had significant near-burner homogeneous-gas-phase reaction zones. The global CO emission index of the PME flames was higher than that of diesel flames at equivalence ratios of 0.4 and 0.6. The NO emission index of the PME flames was almost twice that of the diesel flames. The in-flame concentration profiles highlighted the effects of the significant fuel-bound oxygen content in PME.

This report presents the geochemical data, quality assurance and quality control (QA/QC) results of the re-analysis of lake sediment samples collected from northeastern Saskatchewan (NTS 064-E, 074-A and H). The original lake survey was conducted in 1984 and the re-analysis in 2021. Original survey results are presented in OF 1643. A total of 1,179 lake sediment samples were re-analyzed, covering an area of 18,000 km2, averaging a density of 1 sample per 13 km2. Samples were measured for 65 elements via modified aqua-regia - ICP-MS. To ensure high quality data, the geochemical data was evaluated for contamination, accuracy, precision and fitness-for-purpose. QA/QC results have identified a number of elements to be monitored carefully for future analyses. Overall, the data is of good quality.

This report presents the geochemical data, quality assurance and quality control (QA/QC) results of the re-analysis of lake sediment samples collected from north-central Saskatchewan (NTS 074-A, B, G and H). The original lake survey was conducted in 1986 and the re-analysis in 2021. Original survey results are presented in OF1359. A total of 1,290 lake sediment samples were re-analyzed, covering an area of 17,000 km2, averaging a density of 1 sample per 13 km2. Samples were measured for 65 elements via modified aqua-regia - ICP-MS and 35 elements via INA analysis. To ensure high quality data, the geochemical data was evaluated for contamination, accuracy, precision and fitness-for-purpose. QA/QC results have identified a number of elements to be monitored carefully for future analyses. Overall, the data are of good quality.
